This invention relates to mouth wipers. The invention is particularly adapted for mouthpiece wipers for use in connection with linotype machines of the Mergenthaler type, i and it is an object of the invention to provide an improved mouthwiper of the character described which will be easy to manufacture, simple in operation and highly efficient in its functioning. A. further object of the invention is to provide an improved mouthpiece wiper which is adapted for vertical movement across the face of a mouthpiece of a metal pot of the linotype machine.

A further object of the invention is to provide an improved mouth wiper adapted for actuation in response to movement of the ejector lever, the movement of the mouth wiper being actuated by the ejector mechanism through a lost motion connection,

whereby the wiper will act only upon a portion of movement of the ejector lever.

A further object of the invention is to provide an improved wiping portion of the mouthpiece wiper, which portion includes the provision of a flexible wiping piece resiliently held in taut position and which is readily removable from or replaced on the structure.

Other important objects of the invention include the combination and relation of parts whereby the whole forms an efficient mechanism having few parts and being strong and durable.

Other numerous objects and features of the present invention will be apparent from a consideration of the following specification taken in connection with the drawings, in

Fig. l is a perspective view of our present invention as applied to a metal pot and operable by an ejector lever. The relative positions'of' the metal pot and lever being illustrated without resorting to a complete illustration of the intricate mechanism of any particular form of linotype machine.

Fig. 2 is a front plan view of the present invention.

Fig. 3 is a side elevation of'the same.

Fig. 4 is a sectional view taken on the lines 4-4 of Fig. 3. e a I Fig. 5 is a detail sectional viewtaken on the lines 5-5 of Fig.2.

Referring more particularly to the drawings, there is illustrated in Fig. 1, a metal pot 10 in association with an ejector lever-11, both of which are conventional portions of a linotype machine of the Mergen'thale'r type, and which in association with the linotype machine assume the relative positions herein illustrated. The intricacies of the mechanism'of the linotype machine are such that a complete disclosure of all portionsof the machine would complicate rather than clarify the application and operation of our present invention, and it is understood that the ejector lever and the metal pot herein disclosed form no part of our present invention, the invention being applicable to many'forms and varieties of linotype machines, ejector levers and metal pots, without departing from the spirit or scope of the invention. i

Upon the front of the metal pot 10 there is illustrated the usual mouthpiece 12 which is provided with a plurality of apertures '14 through which hot metal is forced into moulds carried by a mould 'disc, which goes forward into place and is followed by the pot which moves forward also to bring the mouthpiece into contact with a mould when the casting operation takes place. The desirability of means for wiping the mouth after each such operation will be readily appreciated, and efforts to produce sucha device have resulted in complicated and. ineflicient apparatus operating upon a horizontal movement of a wiping member, rather. than a simple vertical movement of the member herein disclosed.

Our invention includes the provision of a base 20 having a-horizontal extending arm'21 apertured for the reception of a securing threaded member 22 by means of which the base 20 is secured to the front edge of the metal pot. Extending through the sides of the base 20, a pair of threaded members 23 are provided, by rotation of which adjustment of the base 20 may be had; the inner extremities of the members 23 being adapted to abut the sides of the metal pot 10 and thus adjust the angular relation of the base with respect thereto.

Pivotally mounted to the base 20, an arm 24 is provided suitably secured thereto for pivotal movement by a screw as at 25. A stop 26 is also provided on the base 20 adapted to limit the forward movement of the arm 21; its rear movement being radially limited by the head of the rear adjusting screw 23. Intermediate the ends of the arm 24, a rearwardly extending portion 27 is provided to which an operating lever 28 may be secured by the provision or an extending screw member 29. Adjacent the arm 27 a hook 30 is provided to which a contraction spring 31 may be secured its opposite end being secured to the metal pot 10 through the provision of a vertically extending supporting arm 32. Spring 30 is adapted to normally hold the arm 24 in vertical position as illustrated in Fig. 1 while the operatin lever 28 is adapted to cause the arm 24 to move in a counter clockwise direction with respect to the base 20 about the pivot point 25.

Carried upon the fr e outward end of the arm 24, a horizontally extending arm 34 is provided extending through the arm 24 and being secured thereto by suitable threaded means as at 35. Adjacent the arm 24, the arm 34 is apertured to receivetherethrough a radially extending member 36, the outer end of which is provided with a projecting pointed pin 37 adapted to engage one end of a wiping member 38 which includes a backing of durable flexible material such as leather illustrated at 39 and a face of suitable wiping material such as cotton as at 40.

The opposite end of the arm 34 is cut out as at 41 to form a shoulder over which an arm 42 is provided lying in the same plane as that of the arm 36; the free end of which is provided with a pointed projecting pin 43 similar to the pin 37 on the extremity of the arm 36. The arm 42 is however, inclined outwardly and formed of suitable flat spring material. The arm 42 is secured to the arm 34 by the externally threaded member 44 receivable within the arm 34. It will be readily seen that upon tightening of the member 44 the arm 42 is received more securely within the shoulder formed by the recess 41 and tends to move outwardly, thus increasing the tension on the leather portion 39 of the wiping portion 38.

For urging the cotton wiping surface of the wiper 38 against the apertures 14 of the mouthpiece 12, there is provided between the material 40 and the flexible backing 39 a suitable flat leaf spring designated as 140 in Figs. 2 and 5. It will be understood that the curvature of the leaf 140 is such that the center portion is arranged to normally extend the center of the wiping surface 40 against the apertures; thus, upon action of the device, the spring is bent by bearing against the mouthpiece 12 and thus complete and even contactof the wiping surface with the apertures 14 is assured.

The operating arm 28 is adapted to extend rearwardly from the metal pot 10 and is cut out as at 45 to provide a hook end 46 adapted to be received over the projecting portion 47 carried by the ejector lever 11. The forward end of the cutout portion 45 of the arm 28 is provided with an adjustable abutment member 48, whereupon the position of the lever 11, at which movement of the arm 28 is instigated may be predetermined.

The operation of the device is as follows:

After the mould disc has contacted with the mouthpiece 12, the ejector lever moves forwardly, whereby the pin 47 strikes the abutment piece 48 moving forwardly the lever 28, which, by its attachment to the arm 24 causes the arm to move in a counter-clockwise direction with respect to its base 20, thus moving forwardly and downwardly the arm 34 carrying the wiping member 38. The arrangement is such that the wiping member 38 is caused to move vertically across in contact with the apertures 14 of the mouthpiece 12. At the end of the downward movement of the arm 34, the ejector lever reverses its movement, thus permitting the arm 24 to raise in response to contraction of the spring 31. The lost motion connection between the arm 28 and the ejector lever 11 is such that the upward movement of the arm 34 is wholly in response to the spring 31. The length of the operating lever 28 is such that the rearward movement of the ejector lever 11 causes contact of the pin 47 with the hook end 46 of the lever 28; the hook thus provides for the return movement of the wiper, should the spring 31 become inoperative.

Thus, it may be readily seen that there has been provided a novel and improved mouth wiping mechanism which is simple in construction and operation and which will accomplish a long desired vertical wiping movement for use in connection with the mouthpiece of the metal pot on a linotype machine, and which is actuated by the ejector lever and thus accurately timed for coopcration with the mould disc movement.

It will be readily understood that nu1nerous changes and modifications in the structure of the invention as herein illustrated, and the full use of equivalents may be resorted to without departing from the spirit or scope of the appended claims.
